Can this control open, edit and save Excel File from Code.
Open a File from code and not in Page_Init event.

Such an exposed method, which returns the value from the ExportOutput, would be useful to further enhance the exporting capabilities of the RadGrid control. A very practical example would be to export numerous RadGrid controls into one Excel file.

The problem is similar and related to https://feedback.telerik.com/aspnet-ajax/1377444-getting-webresource-axd-not-found-error-404-when-searching-for-windows7-sprite-grid-png

The checkboxes decorated with RadFormDecorator appeared double in Classic rendering after upgrading to Firefox 63.

Steps to reproduce:
1. Upgrade to Firefox 63
2. Run the following setup
        <telerik:RadFormDecorator runat="server" DecoratedControls="CheckBoxes" RenderMode="Classic" />
        <div>asp:Checkbox</div>
        <asp:CheckBox ID="chkApproved" runat="server" Text="asp:Checkbox" />

        <div>Html Input</div>
        <input id="chkApproved1" type="checkbox" name="chkApproved" />

======================================

Solutions found so far:
1) Use RadFormDecorator in Lightweight RenderMode:
     <telerik:RadFormDecorator runat="server" RenderMode="Lightweight"/>

2) Set the RadFormDecorator's DecoratedControls="All":
     <telerik:RadFormDecorator runat="server" RenderMode="Classic" DecoratedControls="All"  />

3) Set the ControlsToSkip="CheckBoxes"
      <telerik:RadFormDecorator runat="server" RenderMode="Classic" ControlsToSkip="CheckBoxes"  />

4) Or add the following CSS overwrite to the page:
        <style>
           .rfdCheckboxUnchecked, .rfdCheckboxChecked {
               padding: 0 !important;
               background-image: none !important;
           }
       </style>

You can configure the confirm dialog through a ConfirmText property that defines the confirmation text. The boolean result can be exposed in the arguments of the click event. If there is a RadWindowManager on the same page a radconfirm should be used otherwise - the browser one.

For the time being the functionality can be achieved manually as illustrated in this demo - http://demos.telerik.com/aspnet-ajax/button/examples/confirm/defaultcs.aspx

Hello,

There seems to be a bug with the RadEditor "Find and Replace" feature. I have recorded a screencast available here documenting the issue and will also provide below the information written: https://www.screencast.com/t/MXFawxIPp

Reproduction Steps:

• Open: https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
• Navigate to HTML view
• Click "Find and Replace" or press ctrl+f
• In the Find and Replace window, navigate to the replace tab
• In the Find field put an html tag (For example '<img' )
• In the Replace field put an html tag you with to convert that tag to (For example '<picture' )
• Press Replace All

Expected: '<img' is replaced with '<picture'

Actual:'<img' is replaced with '&lt;picture'

Notes:This seems to be an issue with encoding as &lt; is a less than tag. As you can see in the video, I do not think there is a way to escape the character to allow it to be replaced correctly. If you have additional questions, please ask.

 

Best Regards

Can be reproduced with the code below:

<telerik:RadEditor runat="server" ID="RadEditor1" >
    <Content>
   Here is sample content!
    </Content>
</telerik:RadEditor>
 
<input type="button" value="Set Focus On RadEditor" onclick="SetFocusOnRadEditor(); return false;" />
<script type="text/javascript">
    function SetFocusOnRadEditor() {
        var editor = $find("<%=RadEditor1.ClientID%>"); //get a reference to RadEditor client object
            editor.setFocus(); //set the focus on the the editor
    }
</script>


The problem is not reproducible when the ContentAreaMode is set to DIV or in the other browsers.

Workaround

<telerik:RadEditor runat="server" ID="RadEditor1">
    <Content>
    Here is sample content!
    </Content>
</telerik:RadEditor>
 
<button type="button"  onclick="SetFocusOnRadEditor()">Focuse On RadEditor</button>
<script type="text/javascript">
    function SetFocusOnRadEditor() {
        var editor = $find("<%=RadEditor1.ClientID%>");
        if ($telerik.isChrome) {
            var iframe = editor.get_contentAreaElement();
            iframe.contentWindow.document.body.focus();
        }
        else {
                editor.setFocus();
        }
    }
</script>

The new MultiColumnComboBox control does not have any server side events.  Can you provide the same server side event that you have for the ComboBox? 

Code snippets coming after remove table style from insert table popup in chrome,ie,ff.

I am facing a big problem in editor please give any solution.

Link: https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

Steps to reproduce

Step 1

Try to insert table from Insert Table from editor toolbar.

Step 2

Right click on cell then click on Table/cell properties. A table wizard popup will come.

Step 3

Click on Table Layouts tab on the table wizard popup.

Step 4

Select any value from table styles drop down.

Step 5

Now you can see  TABLE>TR>TD>RemoveElement on the bottom of the editor.click on RemoveElement .

After click on RemoveElement you can see STYLE>RemoveElement  again click on RemoveElement.

then you can see like below in the editor.

.telerik-reTable-2 { border-collapse: collapse; border: solid 0px; font-family: Tahoma; } .telerik-reTable-2 tr.telerik-reTableHeaderRow-2 { border-width: 1.0pt 1.0pt 3.0pt 1.0pt...........

If you put a radspreadsheet inside a radtabstrip with multipage, the controls do not render properly.

In my scenario, I have a tabstrip embedded within a tabstrip, and a grid in the nested tabstrip.  That works fine.  Once you put a spreadsheet control in the multipage, the controls do not render properly. 

However, I was able to reproduce the results with the first scenario above, which is the most simple.

<telerik:RadMaskedTextBox ID="txtCountryDigits" runat="server" SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="50px" Mask="+###" ValidationExpression="+\d{1}.d{1}.d{1}" MaxLength="4" />
<telerik:RadMaskedTextBox ID="txtPhoneNumber" runat="server" SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="116px" Mask = "(###) ###.####" ValidationExpression = "\(\d{3}\) \d{3}\.\d{4}" />
<telerik:RadMaskedTextBox ID="txtExtension" runat="server"  SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="100px" Mask="x##########" MaxLength="11" />

This only affects the Edge browser as far as I can tell.

The Country Digits and Extension only allow one character to be entered when the MaxLength is set equal to the number of characters in the mask.  You can only enter 1 character if you tab into the control.  Click on the control with the cursor does not allow the entry of any digits.   Removing the MaxLength property allows entry of the full input.

The lines shifts badly after line 10 

You think you are on line 17  but the cursor is on line 16.  Very annoying bug for those using this control.  Please fix and give us an update.

Look the attached file.

After upgrading to new version of Telerik (2016.3.914.35), duplicate checkboxes are displaying. Please refer attached file.

The control RadWindow render his element with incorrect names of css classes:
like he rendered rwTitleBar instead of rwTitlebar, and rwStatusBar instead of rwStatusbar
this bug is produced only when i  use a custom theme. 
please if you have a solution bring that.

When we use the control RadNumericTextBox, we met a issue: right alignment for text works under IE8, but doesn't work under IE 10, still left align in this control.  we tried several methods to try fix this issue, 
<telerik:RadNumericTextBox runat="server" ID="control1" Type="Number" ShowSpinButtons="True" ButtonsPosition="Right" IncrementSettings-Step="10"  NumberFormat-DecimalDigits="0" AutoPostBack="False" CssClass="RightPadding" EnabledStyle-CssClass="RightAligned">
  <DisabledStyle HorizontalAlign="Right" CssClass="RightAligned" />
  <EnabledStyle HorizontalAlign="Right" CssClass="RightAligned" />
  <FocusedStyle HorizontalAlign="Right" CssClass="RightAligned" />
  <ReadOnlyStyle HorizontalAlign="Right" CssClass="RightAligned" />
  <InvalidStyle HorizontalAlign="Right" CssClass="RightAligned" />
  <EmptyMessageStyle HorizontalAlign="Right" CssClass="RightAligned" />
  <HoveredStyle HorizontalAlign="Right" CssClass="RightAligned" />

CSS:
<style type="text/css">
 .RightAligned
  {
    text-align: right !important;
  }

   .RightPadding {
        padding-right:2px !important
   }
</style>

but failed. 

Do you have solution to fix this issue?

Expect your reply!

I recently updated my website with the dll patch telerik  provided for the cryptographic weakness:
http://www.telerik.com/support/kb/aspnet-ajax/details/cryptographic-weakness?utm_medium=email

After the update I found that the pages which were using the RadEditor control and several other controls was not loading and throwing this error:
Parser Error Message: Decryption key specified has invalid hex characters.

Several other controls are throwing this error but I cannot delete controls one by one and check which ones are having this problem.

But I checked for the RadEditor and it was throwing this error. Nothing else is there on the page while testing other than this control.
This does not happen on a plain new website and is happening when we have the sql mermbership and machine key configured. We are using passwordFormat as encrypted in sql membership config and cannot remove machine key.
If you got to test it, then test it on some already configured machine key and sql membership website.

I have attached screenshots for this error and telerik dll patch in use currently.

We are on a production server and we need a solution for this issue ASAP.

I have a problem with the deletecommand of the asp.net radgrid control (Telerik.Web.UI 2019.1.215.40).

This happens only in the latest release of Chrome.

I hope you can replicate this issue and eventually fix it. 

This can be reproduced with the following sample:
